BEER-COOLER.

SPECIFICATION forming part of Letters Patent No. 385,986, dated July lO, 1888.

Application filed February 20,1888. Serial No. 264.587. (No model.)

To all whom t may concern.'

Be it known that l, ALoIs AUFRIoi-ITIG, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Beer-Coolers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

r1`he improvement consists in such construction that either one or more ol' the pipesor elbows may be removed, and, in combination with such construction, a flanged elbow having parts of different lengths, so that one of the flanges may be in line with the sectional post and the other outside such line.

Figure I is a side elevation of the cooler with part of the receiving-pan broken away to show one of the feet. Fig. II is an end elevation with the receivingpan in section. Fig. III is a detail perspective View showing parts of four of the pipes and a single elbow with two of the sectionplates of the standard. Fig. IV is a perspective view of parts of one of the end standards disconnected. Fig. Vis a perspective view of the top of one of the end standards. Fig. VI is a perspective View of the foot ot' one of the cud standards. Fig.VlI is a detail perspective View showing part of an inside standard. Fig. VIII is a detail elevation illustrating the manner of removing one ofthe pipes from the cooler. Fig. IX is a detail perspective view of the top of an interior standard, and Fig. X is a detail perspective view of the bottom ot' the same. Fig. XI is a detail showing means for supporting the parts when removing two or more pipes.

1 is the base-pan, which receives the liquid 'after it has run down the series of coolingpipes. At 2 are shown the end standards, which are composed of removable sections and of the coupling-anges of the shorter ends of the pipes. One of the standards 2 has a foot, 3, which is secured to the base-pan and to blocks 4, formingjaws, between which passes the extended end 5 of one of the pipes 6, said end being coupled to a supply pipe, (not showin) through which cold liquid passes into the pipes 6, which are preferably made of copper. The blocks 4 have at the lower and upper parts similar lugs, 7, for connection with the parts above and below by means of a bolt,

8, passing through the lug and through said part. The foot is made with recesses to -re ceivc the lugs.

The shorter ends, 9, of the pipes 6 are expanded in the central orifice, 10, of a jointflange, 11, so as to make a tight joint between the pipe and the flange, and the longer ends, 12, ofthe pipes are secured in a similar unanner in the joint-flanges 13, which are set at some distance fro-rn the blocks 4, so that the bottom of the tlanges 13 may be at a lower level than the top of the flange 11 of the pipe beneath, and thus while flangejoints are used the pipes can be set very near together-in fact, so as to be in contact with the jointilanges of, the nearest pipes above and below. This nearness of the pipes is a considerable advantage for two reasons-rst, it allowsa cooler ot' a given capacity to be putin a smaller space, and, second, it preventsthe liquid from separating into round streams or drops', as there is not space between the pipes for it to do so. The elbows have a long leg, 14, and a short leg. 15, so as to adapt them for application to the shorter and longer ends of the pipes 6, and carry joint `lianges 16 and 17, which are connected to the ianges 11 and 13. The tlanges 16 upon the long legs of the elbows are connected to the flanges 11 of the short ends of the pipes by the bolts 8, while bolts 18 connect the iianges 17 to the flanges 13. Any suitable gasket or packing may be used between the flanges to make thejoint tight, such as sheet-lead or rubber. The Iianges 11 have recesses 19 at the corners, in which the lugs 7 fit snugly, and theirv upper and lower edges against the lower and upper edges of the blocks above and below them, so that when the blocks 4 and flanges 11 are connected by the bolts 8 these parts form a solid standard or upright, which may be readily disconnected at any part for the removal of one or more of the pipes 6. The construction also gives means for increasing or decreasing the capacity ot' the cooler at will by the addition or removal of pipes 6. To the upper blocks 4 is secured a fork, 20, having arms 21, in which is set the drip-pan 22. The arms are recessed at 23 to receive a bar, 24, by which the edge of the drip-pan is strengthened and which also serves as a longitudinal stay.

The cooler, except where it is shorter than ordinarily, has one or more standards between the ends. One of these standards is shown in Fig. I of the drawings. and details of the same are shown in Figs. Vll, VIII, IX, and X. This standard has a foot, 25, standing in the base-pan, and upward extensions 26, to receive a block, 27, having a central perforation, 2S, fitting snugly on, the pipe 6. These blocks are placed on the pipes G before they are put in position in the cooler. The extensions 26 embrace the lower block, 27, and preferably extend to the midheight of the block next above.

29 are screws passing through the extensions 2G and screwing in the blocks. lach block 27 rests firmly on the block beneath it.

30 are cleats by which and the screws 29 the blocks are firmly connected together. The cleats have also end bearing upon each other, and th ns strengthen thestandard against transverse fiexure. The top of the standard has a fork, 31., made to fit the outside et' the drippan 22. The arms of the fork have, like the arms 21, recesses 23 to receive the bar 24. The fork issseeured tothe upper one or two blocks, 27, by screws 29 passing through downward extensions 32 and screwing` in the block or blocks. ltwill be seen that by removing two ol' the cleats from one side and removing two of the screws 29 from the other side any ofthe blocks except the uppermost one and the lowermost two may be made freeto slip transversely from between the blocks above and beneath, supposing the pipe to be free at its ends. The ends of the pipes are made free for removal by disconnecting` them from the elbows and by removal ofthe blocks 4, by which they are held in place in the end standards. To prevent the derangenient or strain ol' the remaining pipes when one is removed, l use a cleat, 33, of double the length of the ordinary cleats, (see Fig. VllL) which will overspan the gap made by the removal of one of the bloel;s,and whose ends are attached by the screws 29 to the blocks above and below such gap.

To allow the removal of a number of the pipes and blocks, a longer cleat, 34, may be used, as seen in Fig. Xl. This longer eleatis shown with offsets at 35, so that t-he cleat may be applied before the intermediate cleats, 30, are removed, (only sufficient of the cleats 30 being removed to give place for the attachment of the ends of the cleat 84 to the blocks above and below those to be removed.)

The cold liquid leaves the cooler through the end 3G of the upper pipe, 6. The current may, however, be reversed, if preferred.

The end standards, 2, are similar in construction, except that while in one the blocks 4 are attached to the foot 3, in the other a joint flange, 1l, is attached to the foot.

It will be understood that a great advantage possessed by this cooler is that it may be taken apart and packed closelyin cases and shipped for low-freight rate, and may be put together at the end of its destination by any ordinary mechanic. Each of the separate parts is both light and small, so that they can easily be carried to any part of a building where it is desired to locate the cooler.

l claim as my invention- 1. In a cooler, the combination, with the pipes, of the jointtlanges 1l., and divided blocks 4, embracing said pipes and alternating with and secured to said flanges, as set forth.

2. In a beercooler, the combination of the pipes, a joint-Harige on the end of one pipe having recesses 19, blocks embracing another pipe having lugs 7 lit-ting said recesses, and bolts 8, passing through the lugs and the fianges, substantially as set forth.

4. The combination, in a beer-cooler, of a vertical series of horizontal pipes extending alternately past each other at the ends in opposite directions, a standard at each end formed of thejointllanges ofthe shorter ends of the pipes, and intervening` blocks engaging the longer ends of the pipes, and elbows having legs ot' different lengths connected to the pipes with flange-joints.
